Solresol is based on the tones and sounds Do-Re-mi-fa-sol-la-si, but also uses primary colours and shapes to convey meaning. The fact that sounds and tones can be used together means that more than one meaning can be conveyed simultaneously, making it a favourite with some superbright clades. Other, far more complex languages have been developed with similar characteristics which may convey several mutually contradictory messages at once, few of which are suitable for modosophont use.
